There is 15 years between 2015 and 2030. Do 3.7% times 15 to find the total percent decrease:
3.7 x 15 =55.5.
Hence, the number will decrease by 55.5%.
55.5% of 25,000 + 13,875.
Now, do 25,000-13,875 to find the amount of newspapers SOLD in 2030. 13,875 was the decrease in numbers.
After doing 25,000 - 13,875, you find the the number of newspapers to be sold in year 2030 will be 11,125.
Hope this helps!
